产品介绍
ST8024L
Designed to be compatible with the NDS conditional access system (except ST8024LTR)
ISO 7816, GSM11.11 and EMV 4.2 (payment systems) compatible
IC card interface
3 V or 5 V supply for the ST8024L device (VDD)
Three specifically protected half-duplex bi-directional buffered I/O lines to card contacts C4, C7 and C8
Step-up converter for VCCgeneration separately powered by a 5 V ± 20% supply (VDDPand PGND)
1.8 V ± 6.5%, 3 V or 5 V ± 5% regulated card supply voltage (VCC) with appropriate decoupling has the following capabilities:
- ICC< 80 mA at VDDP= 4.75 to 6.5 V
- Handles current spikes of 40 nA up to 20 MHz
- Controls rise and fall times
- Filtered overload detection at ~120 mA
Thermal and short-circuit protection on all card contacts
Automatic activation and deactivation sequences; initiated by software or by hardware in the event of a short-circuit, card take-off, overheating, VDDor VDDPdropout
Enhanced ESD protection on card side (>6 kV)
26 MHz integrated crystal oscillator
Built-in debounce on card presence contacts
One multiplexed status signal OFF
Non-inverted control of RST via pin RSTIN
Clock generation for cards up to 20 MHz (divided by 1, 2, 4 or 8 through CLKDIV1 and CLKDIV2 signals) with synchronous frequency changes
Supply supervisor for spike-killing during power-on and power-off and power-on reset (threshold fixed internally or externally by a resistor divider
